The Alpha-1 fireplace insert is a vintage wood-burning heating unit invented by J. Darrel Johnson in the early 1980s (often associated with the Lewiston and Clarkston area of the Pacific Northwest).
Key Details
• Design Concept: Unlike standard air-tight wood stoves that restrict airflow to make wood smolder, the Alpha-1 was designed to burn hot and fast with plenty of air to consume organic vapors before they could escape up the chimney.
• EPA Certification Status: Because it burned too quickly and lacked a traditional closeable draft control to slow down combustion, the Alpha-1 was not able to pass standard U.S. Environmental Protection Agency (EPA) emissions certifications.
